The timing of Angela Saini’s recently published book, Inferior: How Science Got Women Wrong and the New Research That’s Rewriting the Story,[*] seems almost prescient following the publication of the Google memo. Once again, science has been invoked to demonstrate that inequalities between men and women exist because of biological difference instead of lingering prejudices about women’s capability. But, as Saini cautions us, such science isn’t without its biases[†] nor is there necessarily consensus on these findings. In Inferior, Saini seeks to provide insights into controversial studies and theories existing in several scientific disciplines that intimate or have claimed that huge biological gaps exist—ones reinforcing damaging stereotypes—and the new research challenging these findings, even when the facts don’t readily dispel such stereotypes.
When they do, however, the results can be quite eye opening. Among the disciplines that Saini investigates, evolutionary biology has greatly altered its view of women, in no small part due to women scientists. Charles Darwin argued that the pressure only men experienced to obtain mates drove evolution, cementing male superiority to women in every way. Men became hunters, while women, passively engaged in childcare, evolved only because they inherited some of their father’s better qualities. For Darwin, men’s preeminence in all fields proved his point.[‡] Recent studies of increasingly rare modern hunter–gatherer groups, however, reveal cultures where men are caregivers and women are hunters, disputing the idea that such roles are predestined. Indeed, scrutinizing these populations (not to mention animal populations[§]) also contradicts the notion that females are universally monogamous.
However, some areas of study still are poorly understood and others hotly debated. Notably, the role of sex hormones (responsible for sexual development and reproduction) remains less clear. Once thought to be the agents that made men masculine (testosterone) and women feminine (estrogen and progesterone), it’s now understood that these hormones are produced by the gonads of both males and females, albeit in differing amounts. While this discovery dismissed the view that masculinity and femininity were opposites, lingering questions about how these hormones interact within our bodies and affect our minds remain. The theory that sex hormones create significant differences between the brains of male and female fetuses, predisposing them to certain roles, is among the more controversial topics. However, it’s important to recall that the roles of culture and child rearing cannot be ruled out in such cases. And while “small behavioral sex differences” associated with testosterone have been demonstrated in young children (72), most studies tend to show more overlap than difference in typical child development.
Inferior serves as a much-needed corrective to assumptions that science provides clear, objective evidence that significant differences exist between women and men. As science strives to gain a clearer picture of women, it’s more than apparent that women are far from inferior. Indeed, the theme of humanity’s plasticity runs throughout Inferior, suggesting that men and women have more in common than not. And that, indeed, is a great discovery.

[†] Saini observes that the biases that kept women from participating work likely prejudiced science’s objectivity. Women in science, regardless of how underrepresented they are due to social disparities (ranging from childcare to gender bias and sexual harassment), has influenced how science is performed, with new ideas being considered and old ones challenged, very often by women scientist. (10).
[‡] Saini argues here (and elsewhere when disputing how the Google memo got the science wrong) that Darwin was hardly the only man of his time to conflate structural inequality with biological differences (14–8).
[§] That’s not to say all species engage in promiscuous behavior, just that it’s incorrect to assume that all females are monogamous (136–7).
